I have a 30yr mortgage with 5.875% interest rate. The original loan amount was $85,360, I've had the loan for 8 1/2 years, and the current loan balance is $69,069. My monthly P/I payment is $504.94, and I pay $150-200 extra on the principal every month.
I have no plans to ever sale the house & I have excellent credit. So, with what the rates currently are, 3.00+ percent, should I [url=http://www.mortgagefit.com/refinance.html]refinance[/url] to a 15yr fixed rate or should I just stay at my current rate & continue to pay the extra toward the principal?
